AbstractMechanical breathing motions have a fundamental function in lung development and disease, but little is known about how they contribute to host innate immunity. Here we use a human lung alveolus chip that experiences cyclic breathing-like deformations to investigate whether physical forces influence innate immune responses to viral infection. Influenza H3N2 infection of mechanically active… Continue reading Mechanical control of innate immune responses against viral infection revealed in a human lung alveolus chip

Indices of #Diet Quality and Risk of Lung #Cancer in the Women’s Health Initiative Observational Study
Prospective evidence on associations between diet quality indices and lung cancer risk is limited, particularly among older women. ObjectivesWe investigated associations between 4 diet quality indices [Healthy Eating Index-2015 (HEI-2015), Alternate Healthy Eating Index 2010 (AHEI-2010), alternate Mediterranean Diet (aMED), and Dietary Approaches to Stop Hypertension (DASH)] and lung cancer incidence and mortality in the… Continue reading Indices of #Diet Quality and Risk of Lung #Cancer in the Women’s Health Initiative Observational Study
Delayed #antibiotic prescribing for #respiratory tract infections: individual patient data meta-analysis
To assess the overall effect of delayed antibiotic prescribing on average symptom severity for patients with respiratory tract infections in the community, and to identify any factors modifying this effect. Design Systematic review and individual patient data meta-analysis. Data sources Cochrane Central Register of Controlled Trials, Ovid Medline, Ovid Embase, EBSCO CINAHL Plus, and Web… Continue reading Delayed #antibiotic prescribing for #respiratory tract infections: individual patient data meta-analysis
Vitamin #D supplementation to prevent acute respiratory #infections: a systematic review and meta-analysis of aggregate data from randomised controlled trials
A 2017 meta-analysis of data from 25 randomised controlled trials (RCTs) of vitamin D supplementation for the prevention of acute respiratory infections (ARIs) revealed a protective effect of this intervention. We aimed to examine the link between vitamin D supplementation and prevention of ARIs in an updated meta-analysis. Methods For this systematic review and meta-analysis,… Continue reading Vitamin #D supplementation to prevent acute respiratory #infections: a systematic review and meta-analysis of aggregate data from randomised controlled trials
Broadened Eligibility for #Lung #Cancer Screening Challenges and Uncertainty for Implementation and Equity
In 2013, the US Preventive Services Task Force (USPSTF) recommended annual lung cancer screening with low-dose computed tomography (CT) in US adults aged 55 to 80 years who currently smoke or formerly smoked with a 30 pack-year history, and for those who formerly smoked, quitting within the past 15 years (grade “B” recommendation).1 In this… Continue reading Broadened Eligibility for #Lung #Cancer Screening Challenges and Uncertainty for Implementation and Equity
Calculated indices of volatile organic compounds (VOCs) in exhalation for #lung #cancer screening and early detection
Breath analysis is a promising noninvasive technique that offers a wide range of opportunities to facilitate early diagnosis of lung cancer (LC). Method Exhaled breath samples of 352 subjects including 160 with lung cancer (LC), 70 with benign pulmonary nodule (BPN) and 122 healthy controls (HC) were analyzed through thermal desorption coupled with gas chromatography-mass… Continue reading Calculated indices of volatile organic compounds (VOCs) in exhalation for #lung #cancer screening and early detection
#Cancer Statistics, 2021
Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths in the United States and compiles the most recent data on population‐based cancer occurrence. Incidence data (through 2017) were collected by the Surveillance, Epidemiology, and End Results Program; the National Program of Cancer Registries; and the North American Association of… Continue reading #Cancer Statistics, 2021
Distinct developmental pathways from blood #monocytes generate human #lung macrophage diversity
The study of human macrophages and their ontogeny is an important unresolved issue. Here, we use a humanized mouse model expressing human cytokines to dissect the development of lung macrophages from human hematopoiesis in vivo. Human CD34+ hematopoietic stem and progenitor cells (HSPCs) generated three macrophage populations, occupying separate anatomical niches in the lung. Intravascular… Continue reading Distinct developmental pathways from blood #monocytes generate human #lung macrophage diversity
Chest x-ray findings and temporal #lung changes in patients with #COVID-19 pneumonia
Chest CT scan and chest x-rays show characteristic radiographic findings in patients with COVID-19 pneumonia. Chest x-ray can be used in diagnosis and follow up in patients with COVID-19 pneumonia. The study aims at describing the chest x-ray findings and temporal radiographic changes in COVID-19 patients.. ..A total of 88 patients (50 (56.8%) females and… Continue reading Chest x-ray findings and temporal #lung changes in patients with #COVID-19 pneumonia
